Re: Backport latest stable virtualization packages to LTS
Hey guys, While I completely agree that any issue related to libvirt, deserves attention, I also need to say that I never had any problems with Ubuntu Cloud Archive for non-OpenStack deployments. All my regular KVM Hypervisors, Trusty and Precise, have the latest Cloud Archive enabled. Ubuntu is a rock solid and Cloud Archive is basically, just a supported backport repository... What possibly could go wrong? Also, OpenStack Compute Node is basically, a KVM Hypervisor. Cheers!

Backport latest stable virtualization packages to LTS
Hello, I actively use the qemu-kvm and libvirt virtualization stack on the latest Ubuntu server LTS release in a number of production systems. This virtualization stack is stable, mature, and provides a great base on which to host VMs. However, it seems that these packages are not updated once an LTS is released, aside from security updates. I know that this is due to the Ubuntu SRU (https://wiki.ubuntu.com/StableReleaseUpdates), however some major bugs have been found that I think satisfy one of the When conditions. For example, I discovered a bug that would cause the on-disk XML for a VM defined by libvirt to not be updated when a snapshot is taken: https://www.redhat.com/archives/libvirt-users/2015-April/msg00078.html The result would be that if the host is rebooted or the VM is shutdown, the next time it starts up, it would use the previous snapshot, thus either failing to start or invalidating the data on the current snapshot. I believe this satisfies the Bugs which may, under realistic circumstances, directly cause a loss of user data bullet point on the SRU page. I would really like to run a stable virtualization system on top of the latest LTS, but it is hard when new stable releases are not available. Would it be possible for Ubuntu to actively support backporting the stable virtualization stack, e.g in a PPA? I see that the Ubuntu Virtualization Team exists on Launchpad, but does not appear to be active: https://launchpad.net/~ubuntu-virt/+archive/ubuntu/ppa Thanks, Andrew Martin -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss
Re: Backport latest stable virtualization packages to LTS
Hey Andrew, Both new QEmu and new Libvirt are available to Ubuntu Trusty, fully supported. Just install your Trusty and run the following commands: add-apt-repository cloud-archive:kilo apt-get update apt-get dist-upgrade or apt-get install ubuntu-virt-server That's it!

If not, then developers can assume that nobody is affected, and so they may not get fixed as there is presumably no upside and only the risk of regression. This bug is very similar, except I can reproduce the problem on precise too: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1403841 From Eric Blake's commentsin the libvirt-users thread above, it sounds like there were a number of improvements in several newer libvirt releases to address problems where the active config was not being flushed to disk. It looks like the particular code path in 1403841 has been fixed, however others seem to exist. I'm not sure how feasible it would be to cherry-pick all fixes for this problem from newer libvirt releases verses supporting a backport of newer stable libvirt.
